FAQs

Can I use any type of oil?

Yes, but vegetable oil works best because it’s clear and has a neutral color. Other oils may create different effects.

How long will the lava lamp last?

As long as you do not shake it and the ingredients remain separate, the effect can last for several hours. After that, you can refresh it with new Alka-Seltzer tablets.

Is this project safe for kids?

Yes, this project is safe for kids, but adult supervision is recommended, especially when handling the Alka-Seltzer tablets.
